9.7 FUSE RATING

There are no user replaceable fuses in the power supply. Internal fuses are sized for fault protection and if a fuse was opened, it would indicate that service is required. Fuse replacement should be made by qualified technical personnel. Refer to Table 9-2 for a listing of the fuses.

Table 9-2: Internal fuses
